  • Title: Arsenic trioxide regulates the apoptosis of glioma cell and glioma stem cell via down-regulation of stem cell marker Sox2.
    Author: Sun H, Zhang S.
    Journal: Biochem Biophys Res Commun; 2011 Jul 08; 410(3):692-7. PubMed ID: 21703238.
    Abstract:
    Knowledge of the mechanism by which arsenic trioxide exerts the anti-tumor effects may help in designing a more effective regimen for therapy. Transcription factor Sox2, a key gene implicated in maintaining the "stemness" of embryonic and adult stem cells, plays an important role in the carcinogenesis and maintenance of glioblastoma. Here, we found that the expression of Sox2 at transcriptional level was decreased during As(2)O(3)-induced glioma cell apoptosis. And, the ectopic expression of Sox2 attenuated the apoptotic effect of As(2)O(3) on glioma cell. Furthermore, As(2)O(3) inhibited the self-renewal of glioma stem cells, and efficiently induces the apoptosis of glioma stem cells, at least, partly through down-regulation of Sox2. These data identify a previously unrecognized mechanism of the anti-tumor effects of arsenic trioxide.
